Pet Simulator 99 Tower Defense Guide: Location, Flying Units, and Rewards

One of the most common questions active players have about Pet Simulator 99 right now is: "Where is the Tower Defense mode?"

It's one of the best ways to earn gems and items, but it's not immediately obvious how to access it if you're new or haven't played in a few updates.

Here is everything you need to know about the PS99 Tower Defense minigame in December 2025.

Is Tower Defense Still Available?

Yes. As of December 2025, the Tower Defense minigame is still a core part of PS99. It has not been removed, but it is located deep in the Void World.

Where to Find It (Location)

To play Tower Defense, you must travel to World 3 (The Void).

Go to the Void World.
Travel to Area 204.
Look for the large portal/gate labeled "Tower Defense."

Note: You may need to complete specific "Rebirth" requirements to enter the Void World if you are a new player.

How to Beat It: The "Flying Units" Strategy

The hardest part of the minigame is dealing with Flying Units. Standard ground pets cannot hit them effectively.

The Strategy:

Equip "Ranged" or "Anti-Air" Pets: You need pets that have projectiles.
Use the "Storm" Ultimate: Save your ultimate ability for wave 10+ when the massive swarms of flying balloons appear.
Place Towers at Corners: Maximize your damage by placing your units on the corners of the path so they can shoot enemies for a longer time.

The Rewards

Why should you play it?

Huge Gem Payouts: It's one of the best non-trading ways to earn Gems.
Exclusive Enchants: You can win exclusive "Tower Defense" enchants that boost your team's damage.
Clan Points: If you are in a Clan, high scores here contribute to your clan battle rank.
